...and bring high power to small packages
"Metal droplet levitated inside the Electrostatic Levitator (ESL). The ESL uses static electricity to suspend an object (about 2-3 mm in diameter) inside a vacuum chamber while a laser heats the sample until it melts. This lets scientists record a wide range of physical properties without the sample contacting the container or any instruments, conditions that would alter the readings. The Electrostatic Levitator is one of several tools used in NASAs microgravity materials science program."
"The Electrostatic Levitator (ESL) Facility established at Marshall Space Flight Center (MSFC) supports NASAs Microgravity Materials Science Research Program. NASA materials science investigations include ground-based, flight definition and flight projects. Flight definition projects, with demanding science concept review schedules, receive highest priority for scheduling experiment time in the Electrostatic Levitator (ESL) Facility."
Researchers have developed a new family of glasses that will bring higher power to smaller packages in lasers and optical devices and provide a less-expensive alternative to many other optical glasses and crystals, like sapphire. Called REAl(tm) Glass (Rare-earth - Aluminum oxide), the materials are durable, provide a good host for atoms that improve laser performance, and may extend the range of wavelengths that a single laser can currently produce.
With support from the National Science Foundation (NSF), Containerless Research, Inc. (CRI), based in the Northwestern University Evanston Research Park in Illinois, recently developed the REAl(tm) Glass manufacturing process. NSF is now supporting the company to develop the glasses for applications in power lasers, surgical lasers, optical communications devices, infrared materials, and sensors that may detect explosives and toxins.

Researchers at Chalmers University of Technology and the University of Gothenburg, Sweden, have proposed a way to create a completely new source of radiation. Ultra-intense light pulses consist of the motion of a single wave and can be described as a tsunami of light. The strong wave can be used to study interactions between matter and light in a unique way. Their research is now published in the scientific journal Physical Review Letters.
"This source of radiation lets us look at reality through a new angle - it is like twisting a mirror and discovering something completely different," says...
